BED-SPRING;

Specification of Letters Patent.

Application filed February 10, 1914. Serial No. 817,773.

To all whom it may concern:

Be it known that I, J Acne SCHWARTZMAN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Bed-Springs,

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to charactors of reference marked thereon, which form apart of this specification.

The present invention relates, generally, to im n'ovement's in bed-springs; and, the invention has reference, more particularly, to in'n irovements in bed-springs made from a woven. wire metallic fabric, provided at its respective end portions with a fabric bind ing and gripping element, to which the sharp rough ends of the fabric are secured,

and-in which the same'are concealed, and by means of which the fabric is stretched and supported in the usual framework for suspending the springs in proper relation to a bed, couch or similar article of furniture.

My present invention has for its principal object to provide a novel binding and gripping element for binding and securing the rough edges of a metallic spring fabric, and for providing a means for suspending said fabric in stretched relation to the sirin 'framework. Said bindin and ri ping element being made of an integral flat sheet metal body, the parts of which are struck-up out of the same and so formed and bent as to cooperate to provide the fin-.

islied binding and gripping element, thus providing a cheap and eflicient one-piece construction, and saving all waste of metal in its construct-ion.

A furtherobject of the said invention lies in the novel arrangement and formation of the several parts of the binding and grip ping element, so that when the binding and gripping element is connected with the metallic spring fabric it will receive and envelop the sharp rough'ends of the same, and

firmly grip said ends, being retained in such relation to said fabric by the novel cooperation and interlocking of the various parts of the binding and gripping element.

As thus enveloping and gripping said rough sharp ends of the spring fabric, saidbind- Patentea v ve, i914.

ing andgripping element is adapted to conbe clearly understood from the following de-.

tailed description of the present invention.

\ The invention consists, primarily, in the novel binding and gripping element for woven wire metallic spring fabrics herein:

after set forth; and, the invention consists, furthermore, in the several, novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of thesame, all of which will be. hereinafter morefully described, and then finally embodied in the claims which. are appended to; and which form an essential part of this specification. i

.TllG present invention is clearly illustrated in the accompanying drawings, in it which Figure 1 is a plan view of one end-portion of a woven wire metallic spring fabric connected with the novel binding and gripping element embodying the principles of my present invention; Fig. 2 is a detail plan view of a portion of the under or opposite side of said novel binding and gripping element. vFig. 3 is a detail cross section taken on line 3+3 in said Fig. 1; Fig. 4: is another detail cross section taken on line 4-4 in said Fig. l; and Fig. 5 is a detail longitudinal section taken on line 55 in said Fig. 1; all of said above mentioned views being. drawn .on an enlarged scale.

Similaf characters ofreference are employed in all, of the above escrlbed views to indicate corresponding parts. V, I

Referring now to the several figures of the drawings, the referencech aracter 1 in jdicates any suitable form of. woven wire" metallic spring fabric, such as'ls commonly 0 body or plate 3.

used in the construction of bed-springs, and 2 indicates the free sharp and rough end portions of the wire strands from which said fabric is made. 1 V

The novel binding and gripping element comprises a main body or plate 3. main body or plate 3 is provided with a plurality of longitudinally disposed curvilinear cuts so disposed that said main body or plate 3 may be doubled back upon itself to provide a forwardly extending top-plate 4t, leaving, however, a plurality of rearwardly extending tongues 5, the same lying, preferably, in the plane of said main The forward edge of said main body or plate 3 is provided with a lurality of upwardly turned teeth 6.

truck out of said top-plate 4, adjacent to the free marginal edge of the same, are a plurality of downwardly and forwardly eX- tending gripping tongues 7, the same being of greater width at their extremities than at their bases. In bending down said grip ping tongues 7 a plurality of receiving openings 8 are likewise formed in said topplate a, adjacent to the free marginal edge thereof. These receiving openings 8 register with the extremities of said upwardly turned teeth 6 of said main body or plate 3.

The free sharp and rough end portions 2 of the wire strands, from which the spring fabric 1 is made, are laid across the teeth 6 so asto be lodged in the spacesG' therebetweenhen said forwardly extending top-plate is then doubled back upon said main body or plate 3, it is spaced slightly away from the latter to provide an intervening receiving space or chamber 9 in which said sharp and rough end-portions 2 of the spring fabric 1 are concealed, and as the top-plate 1 is bent down to its normal position the free ends of said teeth 6 pass through said receiving openings 8, so that the same project above the upper surface of said top-plate at, whereupon the said free ends of the teeth 6 are'bent rearwardly and downwardly upon the upper surface of said top-plate 4 thereby interlocking and securing said free ends of the respective main body or plate 3 and said top-plate at in their normal associated relation. When the forward end of said top-plate 4: is thus secured, the free downwardly turned eX- treinities of the gripping tongues 7 press downwardly upon the strands of wire forming the end-portions 2 of the spring-fabric 1, as the same diverge within the receiving space or' chamber 9 after passing through the spaces 6 between the teeth 6, and thus said end-portions 2 are gripped and held securely between the ends of said gripping tongues 7 and said main body or plate 3 against withdrawal from said receiving space or chamber 9 through said spaces 6 between the teeth 6. To provide a further Said grip upon said end-portions 2 of the spring fabric 1, the extreme free edge of said topplate 1 is bent downwardly against the tions 2 of the spring fabric 1 are concealed within the interior of the binding and gripping element, and at the same time firmly gripped thereby so that the spring fabric is properly spread and ready for attachment to the springs suspending framework. The marginal edges of said topplate 4: bordering said curvi-linear cuts are depressed to form downwardly extending closing-portions 11 which register upon said main body or plate 3, thus closing the interstices between said top-plate 4L and said main body or plate 3 formed by said curvilinear cuts, and thereby closing said intervening space or chamber 9 against the entrance of dirt or vermin at such points, at the same time maintaining said top-plate 4i spaced away from said main body or plate 3 so as not to constrict said space or chamber 9. In order to further prevent the separation of said top-plate a from said main body or plate 3, and to further secure the said parts in their normal associated relation to each other, there are provided a plurality of clamp-lugs 12 which are struck up in part out ,of said main body or plate 3 and in part out of said tongues- 5 extending rearwardly therefrom. These clamplugs 12 are turned upwardly and over said closing-portions 11 and upon the upper surface of'said top'plate 4c, thereby preventing any separation of the latter from said main body or plate 3 at their rear edges. In striking out said clamp-lugs 12, openings 13 are left which extend partly into said tongues 5. the hook-end 14- of helical springs 15 which are ordinarily used to suspend the spring fabric 1 upon the usual supporting frame-work. Extending outwardly from the ends of said main body or plate 3 are end-members 16 which are turned upwardly and over the upper surface of said top-plate 4, thus closing the open ends of the said intervening space orchamber 9, provided between the main body or plate 8 and said top-plate 1-, against the entrance of dirt or vermin therein at such points.

From the above description it will be apparent that the present invention provides a very strong and eflicient one-piece binding and gripping element for woven wire spring fabrics, which not only grips and binds the rough and sharp end-portions of the fabric, but which also is so constructed as to be vermin and dirt proof; and, furthermore, the novel construction of the device provides integral interlocking parts which firmly secure the device in proper form and in proper These openings serve to receive prising a main body doubled upon itself to provide an intervening chamber in which the ends of said spring fabric are received, means connected with the superimposed forward longitudinal edges of said main-body for interlocking the same together, and internal gripping means extending downwardly from the upper portion of said doubled body for engaging the strands of the spring fabric lodged in said chamber.
